Ok I have searched and called and I'm at my wits end. Door plate says FS5W71B trans. No one sells a rebuild kit for a FS5W71B. Apprently the front have big bearings in the FS5W71B in later 720s that are the same as the FS5W71C. If there is a rebuild kit for the 71B can someone please give me a link to it, or will the one for the 71C work, because all the parts stores say it does.
